FXS modules for 2400 cards
Each module supports up to four (4) FXS channels, and up to four (4) analog device such as an analog phone or tradition fax machine.​

  • FXO ports are used to connect directly to PSTN telco / provider lines. They are used to connect your analog phone system to the PSTN. They receive ring voltage from FXS devices.

FXO modules for 2400 card
Each module supports up to four (4) FXO channel, and one (1) PSTN trunk lines.​

Gateway Applications

PSTN-Trunking

Use inside a server of your choice, powered by Linux/Windows, to create a SIP-TDM Gateway with your legacy analog based PBXs to replace expensive analog line connections with SIP trunking to allow reduced call costs, reduced line rental, and bring extra flexibility and disaster recovery.

SIP Trunking

Use inside a server of your choice, powered by Linux/Windows, to create a SIP-TDM Gateway to allow IP-PBX to route calls to traditional PSTN.

Fax and Legacy Gateway

Use our Sangoma cards in your choice of hardware to connect legacy analog equipment like fax machines, door-bells or analog phones to your IP-based network.

Call Forwarding

Monitor and record telephone conversations for lawful call interception. Use your choice of software, including Sangoma’s own TDM SDK dedicated for call tapping.

Analog Card Features
